SAFETY DEVICE, FOR FIREARMS, &c;

Specification of Letters Patent.

Patented Aug. 3, 1909.

AppLication filed May 21, 1909. Serial No. 497,505.

To all whom it may concern:

Be it known that I, PAUL MAUSER, privy councillor of commerce, a subject of the King of Vlfrtemberg, residing at Oberndorf-onthe-Neckar, in the Kingdom of Vrtemberg, Germany, have invented certain new and useful Improvements Relating to Safety Devices for Firearms, Especially Automatic Firearms, of which the following is a full, clear, and exact description.

The invention relates to a safety device for fire-arms, especially automatic lire-arms, in which the sear held in the safety position by a lever situated on the exterior of the casing and capable of being held in the safety position.

According to the invention the arrangement is such that thelsafety lever, acting, by means of a wing or arm, as a detent on the sear, 'is held in its safety position against the pressure of a spring, which latter pushes the safety lever into its position of rest when the locking device is released, so that a single handle effects the unlocking and releases thc safety mechanism. i

ln the accompanying drawings two cony structions of the invention are shown.

Figures 1 to 5 show the invention applied to a weapon with a movable barrel, and Figs. 6, 7, 8, to a Weapon with fixed barrel and a socalled breech slide. Fig. 1 is a side view of the weapon closed and in the non-safety posltion. weapon partly in section and -set to safety. Fig. 3 Vshows a plan and side viewof the safety lever with its projection or arm for securing the Sear. Fig. 4 shows a rear and side view of the resilient securing arm for the safety lever.' Fig. 5 shows a side view and planof the spring. Fig. 6 shows the safety mechanism applied to a weapon with a fixed barrel and in the non-safety position. Fig. 7 is-a similar view to Fig. 6 but-showing the weapon set to safety, and Fig. 8 is a section on the line A-A of Fig. 7.

The safety device of the weapon, according Ato the construction shown in Figs. 1 to 5,

consists essentially of a rotatable safety lever a, which is arranged on the left hand side of the stock g, underneath the rear end of the guide al for'the breech frame h, and is held inv i the safety position by a resilient securing arm or detent v located in the same position underneath the lever. The safety lever has an arm al projecting toward the interior of the casing, which arm is preferably made in- Fig. 2 shows the rear part of theA tegral with the lever plate and is provided at its rear end with a notch u2. The position of this arm u1 on the safety lever u is such that,- When said lever is slanting downward and is consequently in the safety position, the arm u1, with its notch u2, is underneath the rear end of the sear t, and thereby holds the llatter. The safety lever u is held in the safety position by the nose v1 of the resilient detent c engaging in a corresponding cavity u* at the back of the safety lever u. To effect the release it is only necessary to press on the press piece v2 provided for this purpose on the resilient arm e, whereby its nose v1 will be pushed out of the corresponding cavity The plate spring w located inside the casing acts on the front end of the arresting arm u1 and, by engaging a notch a3 in the latter with its narrow nose w1, prevents the safety lever u from being moved sidewise and thus holds it in position. This spring also, when the safety lever u is released, causes the latter to bell-crank lever u, u serves as a safety lever, the arm uf* of which extends longitudinally to the trigger guard and carries at its extreme end the press piece a5 which is adjacent to the trigger tongue, so that it can be comfortably operated by the thumb when the weapon is being used. The other arm u of this safety lever lis bent up at right angles or thereabout, so that it lies behind the simllarly bent up armJl of the scar t0 when, thc safety lever is in the engagement posltlon (Fig. 7). A spring arm v0 is provided to hold the safety lever a4, u", i n this position of engagement, said arm/0 belng in the sha e of a bar or long flat spring located inside t e view to facility of operation, is situated in a position adjacent to the press piece wen the safety lever 11,4, u at the front part of the butt'i. e., in the vicinity of the trigger. .An important feature of this construction of The spring armv" safety mechanism is that the arm u of the safety lever a4, u, acting as a detent on the sear t,is also ca able of arresting the breech p sponding recess would have to be provided on the inner edge of the breech frame. As regards the construction shown it should be further mentioned that the spring wo, which holds the lever u, u, in the safety position and which, u on the arm v0 being released,

2. a movable breech block, a safety lever adaptcauses the sa ety lever to assume its position of rest, is in the form of a bent plate spring which also actuates the sear, While one end of this spring acts on the safety lever 11,4, u, the other front end presses up against the sear t0 in order to hold the arm t1 in engagement with the nose on the firing pin, see` Fig. 7.

What I claim as my invention, and desire to secure by patent is:

1. In a re-arm, the combinationof a sear, asafety lever adapted lto act as a detent` for the sear, a spring tendin to move said safety lever to the posltion of ring, and an arresting device for holding said safety lever against the tension of its spring in the safety position whereby upon releasing said arresting device the safety leversprings back to its irmg osition.

n a lire-arm, the combination of a sear,

ed to act as a detent for the sear, a sprmg tending to move said safety lever to the position of firing, and an arresting device for uponv releasing said arresting device the safety lever springs back to its firing osition, and said safety lever bein ada te also to engage said breech block to ock t e same.l 3. n a fire-arm, the combination of a sear, a safety lever adapted to act as a detent for the sear, .a spring tendiner to move said safety lever to the position of firing, and yan arresting device comprising a s ring arm engaging sald safety lever and hol ing it in its safety position against .the tension of lits spring *whereby u on releasing said arresting device the safety ever springs back to its ring positon.

4. In a fire-arm, the combination of a sear, a safety lever adapted to act as a detent for the sear, a spring tending to move said safety lever to the position of firing, and an arresting device for holding said safety lever against the tension of its spring in the safety position whereby upon releasing said arresting device the safety lever springs back to its ring position, said arresting device and said safety lever being mounted near the trigger Aof the fire-arm for convenience of manipulation.

i In witness whereof7 I have hereunto signed my name in the presence of two subscribing witnesses.

PAUL MAUSER.
